" 3 Claims.

- The present invention contemplates the construction of a rubber heel for footwear which will greatly minimize the wear thereof, and prolong its life in a novel manner thus providing a unique and simple construction for the purpose.

One object of my invention is to provide a rubber heel structure which will incorporate therein a rotatable disc for wear purposes and adjustment, the assembly thereof to the heel member constituting the .entire arrangement. The two elements comprising the entire structure are held in place frictionally against rotation; hence, when the disc is worn at a particular point the portion can be positioned away from the recess in the heel portion, thedisc affording a fresh surface, thus causing the combined heel and disc structure to assume a normal, and new or unworn appearance.

Another object of my invention is to provide a heel structure embracing a non-rotatable disc structure which is mounted so that a lip thereof is interfitted to agroove of the said heel member or. element, and having its outer edge in tangential relationshipwith the outer portion of the heel element proper.

Another object of my invention is to provide tongue and groove means in the combined heel and disc structure which will retainone withinsame orretain the the other firmly and lock the same positively against rotation.

Another object of my invention is to provide a disc member which is tapered and of a frustoconical configuration mating with a recess of similar configuration in the heel member proper, the said recess being positioned on the heel member so as to permit the top surface of the disc member to coincide or align itself tangentially with the outer arcuate portion of the heel element proper, the same being firmly retained in place by tongue means within the heel element cooperating with grooved means provided on the frusto-conical surface of the disc element.

Another object of my invention is to provide a heel structure of the aforementioned character which is simple in construction, practical in its use providing adjustment for Wear, and which is of such simple elemental structure as to warrant economical commercial manufacture thereof in quantity production.

Other features, objects and advantages inherent and resident in my invention will become apparent from an examination of the accompanying drawing, having particular reference thereto in the ensuing description, for a complete elucidation of the ,objectsto be attained; wherein like numbers areused to designate like parts, and in which: 7

A v r Referring'to the various figures, a shoe is, gen-' erally, designated l2, and is provided with'a partial leatherheel structure E3 to which is secured my.invention, generally, designated '1, and which is comprised of aheel element proper 2i and a disc element ll. The heel element 2i is of usual construction having two straight sided portions mergingwith an' outer arcuate portion 9, and running intoaii inner arcuate portion 8 adjacent the arch portion or the shoe l2.

The heel 2! is provided, preferably, with a frusto-con1cal recess l5 and, substantially, at its mid-point with a lip l6 adapted to engage the groove i9 of the disc, generally, designated l1; the said disc being also of a frusto-conical configuration, its groove l9 separating the section 18 from the section 20, the surface of which will bear against the bottom portion of the recess IS in the heel member, thus affording friction thruout the conical surface, the beaded and grooved portion as Well as the bottom surfaces of the recess l5 and the portion 20 of the disc 11 assumm' g good M 2,387,029 q .4, frictional engagement which may be pried out or asmuch as I believe the same to be susceptible disengaged. of many alterations, modifications, and improve- When a certain portion of the disc has become ments, I reserve the right to all such modificaworn while in the position at the point M, the tions, alterations and improvements coming said disc may be removed and reset in place with within the scope and spirit of my invention, also a fresh unworn portion coincident with the porthose implied in the accompanying drawing, as tion l4, thus lending to the surface 22 of the heel well as those lying within the purview of the fore- 2| an even and unworn efiect, particularly, at the going disclosure. point l4.
